LUBRICATING JOURNAL-BOX FOR RAILWAY-CAR AXLES.

Specification of Letters Patent.

Application filed May 9, 1905. Serial No. 269,4:93.

To 1/, whom, it may concern:

Be it kn own that I, ANDREW J. MARSHBANK, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Lubricating Journal- Boxes for Railway-Car Axles; and I do cleclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in lubricating journal boxes for railway car axles, especially with reference to the provision of improved means for applying the lubricating-oil to the journal; and it consists in the construction, combination, and arrangement of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of a lubricating journal-box embodying my improvements, and Fig. 2 is a vertical transverse sectional view of the same.

The journal-box 1 is preferably of the form here shown, with a fiat bottom 2 and an opening 3 at its outer end, which may be covered by a suitable closure. (Not here shown.) The upper portions of the sides of the journal-box serve to retain bearing-blocks 4, the lowermost of which bears on the axle-journal 5 and is shaped on its under side to fit the same. In the lower portion of the journal-box are a pair of cylindrical float-rollers 6, which are preferably made of cork or other suitable light material. The same float in the lubricating-oil in the journal-box and are kept in contact with the lower side of the axle-journal and are rotated by the axle-journal when the car is in motion, so that the surfaces of the said float-rollers apply oil continuouslyto the under side of the axle-journal, and hence the latter is kept effectually lubricated. The said float-rollers are held in operative position under and with reference to the axlejournal by means of guides 7, each of which is made from a single strip of sheet or plate metal bent to form end portions 8, vertical guide-arms 9, and an intermediate portion 10. The said intermediate portion of each guide device and the said guide-arms 9 thereof are provided withopenings 11, so that oil may pass freely through them. The guide-arms are on opposite sides of the float-rollers.

Each float-roller guide device is supported on a spring-plate 12, which is arc-shaped and is supported by and on a similarly-shaped supporting-plate 15, provided with upturned end portions 18 to bear against the sides of the journal-box, said plate lying on the bottom thereof. The end portions 8 of the floatroller guide devices, together with the end portions of the springs 12, are riveted or otherwise suitably secured on the said supportingplates, and the latter and the said springplates are provided with openings 14: at their centers, which register with the openings in the intermediate portions of the said guide devices to permit oil to pass freely to the said float-rollers. The spring-plates 12 coact with the guide devices to maintain said float-rollers in contact with the under side of the axlejournal.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requirin a more extended explanation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a longitudinal box, a roller therein to bear against the lower side of the journal, an arc-shaped spring in the bottom of thejou rnal-box and having upturned ends bearing against the sides thereof, and a guide device on said spring, bearing under the roller and having vertical guide-arms on opposite sides of the roller.

2. In combination with a longitudinal box, a roller therein to bear against the lower side of the journal, an arc-shaped spring in the bottomof thejournal-boxandhavingupturned ends bearing against the sides thereof, and a guide device on said spring, bearing under the roller and having vertical guide-arms on opposite sides of the roller, said guide device being made from a single strip of metal bent to form end portions to bear on the spring, the vertical guide-arms, and an intermediate portion.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
